- `str2`: a character string or character string vector . The string(s) to search in `str1`
- `ind`: vector of indexes
- `which`: vector of indexes

### Description

`strindex` searches indexes where `str2(i)` is found in `str1`

for each `k` it exist a `i` shuch that `part(str1,ind(k)+(0:length(str2(i))-1))` is the same string than `str2(i)`. If `which` argument is required it contains these `i`.
